PSYB55 midterm I Questions with
Complete Solutions.
What are the three types of neutrons? - Answer Motor Neurons: communicate motor signals
Sensory neurons: absorb information from the environment.
Interneurons: important for knowledge, memory, problem solving, attention, cognitive
processes in general.
What are the parts that make up a neuron? - Answer Dendrites: the neuro antenna. Part of
the neuron that receives signals from the other neuron.
Axon: "information highway" when a neuron decides to send a signal, signal travels down the
cell body to axon to axon terminals.
Axon Terminals: the point in which the signal transfers to a chemical signal.
- critical for one neuron to talk to another neuron given that most neutrons have a space
between them bridge my chemicals

Describe Dopamine. - Answer Made in substantia nigra and ventral segmental area.
Links to cognition/behaviour:
- high order cognitive functions,
- voluntary movement,
-reward/reinforcement learning.
, associated with: behavior addiction
Describe Norepinephrine - Answer Made in locus coeruleus.
Links to cognition/behaviour:
-arousal as in consciousness.
-Attention.
-Memory, and
-mental flexibility you try new things)
Associated with Alzheimers and depression.
Describe Serotonin - Answer Made in Raphe Nucleus
Links to cognition/behavior: mood.
Low serotonin levels can make someone moody.
symptoms of depression = low levels of serotonin.
Associated with: mood disorders
Describe Acetylcholine. - Answer Made in Basal forebrain.
Linked to: sensory
-processing/attention
-long term & short term memory
long term potentiation
movement (PNS)
- helps process sensory processing and attention which facilitates memory and create new
memories
-critical for movement in the body
Associated with: Alzheimers disease. TO treat, increase acetylcholine.
what is single cell recording? - Answer A neurophysiological method used to monitor the
activity of individual neurons. The procedure requires positioning a small recording electrode
either inside a cell or, more typically, near the outer membrane of a neuron. The electrode
